Supported Hand and Finger Imaging File Formats
Our free hand and finger viewer opens DICOM files from major scanners, plus ZIP and TAR archives, NIfTI exports, and common 8-, 12-, and 16-bit pixel data. Drop a hospital CD folder, USB export, or ZIP into the viewer; raw files stay in your browser.
Archive formats
If your scan came as one big compressed file, drop it directly into the viewer — we unpack it in your browser.
- ZIP — the most common format on hospital CDs and patient-portal downloads
- TAR — common for research datasets
- .tar.gz and .tgz — TAR + GZIP compressed
DICOM transfer syntaxes
The technical format used to encode pixel data inside a DICOM file. Our viewer decodes every common transfer syntax used by clinical scanners.
- Implicit VR Little Endian (1.2.840.10008.1.2)
- Explicit VR Little Endian (1.2.840.10008.1.2.1)
- JPEG Lossless (1.2.840.10008.1.2.4.70)
- JPEG Extended 12-bit (used by i-CAT dental CBCT)
- RLE Lossless
- 8-bit, 12-bit, and 16-bit pixel data
- MONOCHROME1 and MONOCHROME2 photometric interpretations
NIfTI (research / converted scans)
NIfTI (Neuroimaging Informatics Technology Initiative) is the format used by most research and post-processing tools. If you ran your scan through a pipeline like FreeSurfer or fastMRI, you likely have a NIfTI file.
- .nii — uncompressed NIfTI volume
- .nii.gz — GZIP-compressed NIfTI (most common)

Frequently Asked Questions
Can I upload a folder from a hand X-ray CD?
Yes. Drop the DICOM folder directly, or zip it first. The viewer groups files by series and lets you switch between X-ray, MRI, or CT when present.
Does this support finger MRI ZIP files?
Yes. Standard DICOM MRI series and ZIP archives are parsed locally in the browser. MPR and 3D rendering depend on slice spacing and volume quality.
